Department, Industrial Education College, Beni–Suef, EGYPT ABSTRACT Aggregate properties can affect hot mix asphalt properties in different ways. Also, the filler plays an important role in asphalt mixtures behavior. This research represents a laboratory study of the effect of the aggregate type and mineral filler in hot mix asphalt (HMA). The aggregate types used in the mixtures were crushed limestone, crushed gravel and basalt. Two parameters were used to study the effect of the filler on HMA, the mineral filler type and content. Three types of mineral fillers used in the mix which were limestone powder, cement and hydrate limestone powder. The contents of fillers for this study were 4, 6 and 8%. Marshal tests and indirect tensile test were performed to investigate the difference in behaviors of different samples with different parameters that considered in this study. Also this study taking into account that the control mix contains crushed gravel, rough aggregate particles with medium gradation of aggregate and 4% of limestone powder as mineral filler. The results showed that, using basalt gives the highest values of each Marshall Stability, Marshall Stiffness, Marshall Quotient, Stiffness Modulus and the Indirect Tensile Strength of the mix than gravel and limestone. Unlike, using basalt gave the lowest values of each flow, density and air voids than gravel and limestone. The results also, showed that using of cement as mineral filler had good results than other types of mineral fillers and the mineral filler content in the mix shouldn’t increased than 4%. Key words: HMA, Aggregate type, Mineral filler, and Indirect Tensile Strength. Cite this Article: Naglaa Kamal Rashwan.
